問題

  • DIMMの交換中は 、メモリサブシステム全体で手順診断が実行されます。

*> sldiag device run -dev mem

  • SLDIAGテストの完了時に「Random Address Mem Test」というエラーステータスが表示されることがあります。

*> sldiag device status

To see details use: sldiag device status -long

There are still test(s) being processed.

  • さらに調査すると、交換したDIMMとは別のDIMMで修正可能なエラー(CECC)が発生します。
